CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to, and the benefit of, Korean Patent Application No. 10-2021-0122980, filed on Sep. 15, 2021, the disclosure of which is incorporated herein by reference in its entirety.

BACKGROUND Field

The present disclosure relates to a device for providing augmented reality (AR) content, and a method of providing AR content using the same.

Description of the Related Art

Recently, electronic devices and display devices capable of realizing virtual reality (VR) have been developed, and interest in them is increasing. As the next stage of VR, a technology capable of realizing augmented reality (AR) and mixed reality (MR) is also being studied.

AR is a display technology that further increases the effect of reality by superimposing virtual objects or image information on a real-world environment, unlike VR that assumes a completely virtual world.

While VR has been limitedly applied only to fields such as games and virtual experiences, AR has an advantage in that it may be applied to various real-world environments. In particular, AR is attracting attention as a next-generation display technology suitable for a ubiquitous environment or an Internet of things (IoT) environment. AR can be said to be an example of MR, in that it shows additional information of a virtual world mixed with the real world.

DETAILED DESCRIPTION

Aspects of some embodiments of the present disclosure and methods of accomplishing the same may be understood more readily by reference to the detailed description of embodiments and the accompanying drawings. Hereinafter, embodiments will be described in more detail with reference to the accompanying drawings. The described embodiments, however, may have various modifications and may be embodied in various different forms, and should not be construed as being limited to only the illustrated embodiments herein. Rather, these embodiments are provided as examples so that this disclosure will be thorough and complete, and will fully convey the aspects of the present disclosure to those skilled in the art, and it should be understood that the present disclosure covers all the modifications, equivalents, and replacements within the idea and technical scope of the present disclosure. Accordingly, processes, elements, and techniques that are not necessary to those having ordinary skill in the art for a complete understanding of the aspects of the present disclosure may not be described.

Unless otherwise noted, like reference numerals, characters, or combinations thereof denote like elements throughout the attached drawings and the written description, and thus, descriptions thereof will not be repeated. Further, parts that are not related to, or that are irrelevant to, the description of the embodiments might not be shown to make the description clear.

In the drawings, the relative sizes of elements, layers, and regions may be exaggerated for clarity. Additionally, the use of cross-hatching and/or shading in the accompanying drawings is generally provided to clarify boundaries between adjacent elements. As such, neither the presence nor the absence of cross-hatching or shading conveys or indicates any preference or requirement for particular materials, material properties, dimensions, proportions, commonalities between illustrated elements, and/or any other characteristic, attribute, property, etc., of the elements, unless specified.

Various embodiments are described herein with reference to sectional illustrations that are schematic illustrations of embodiments and/or intermediate structures. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Further, specific structural or functional descriptions disclosed herein are merely illustrative for the purpose of describing embodiments according to the concept of the present disclosure. Thus, embodiments disclosed herein should not be construed as limited to the particular illustrated shapes of regions, but are to include deviations in shapes that result from, for instance, manufacturing.

For example, an implanted region illustrated as a rectangle will, typically, have rounded or curved features and/or a gradient of implant concentration at its edges rather than a binary change from implanted to non-implanted region. Likewise, a buried region formed by implantation may result in some implantation in the region between the buried region and the surface through which the implantation takes place.

Thus, the regions illustrated in the drawings are schematic in nature and their shapes are not intended to illustrate the actual shape of a region of a device and are not intended to be limiting. Additionally, as those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present disclosure.

In the detailed description, for the purposes of explanation, numerous specific details are set forth to provide a thorough understanding of various embodiments. It is apparent, however, that various embodiments may be practiced without these specific details or with one or more equivalent arrangements. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring various embodiments.

Spatially relative terms, such as “beneath,” “below,” “lower,” “under,” “above,” “upper,” and the like, may be used herein for ease of explanation to describe one element or feature’s relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or in operation, in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” or “under” other elements or features would then be oriented “above” the other elements or features. Thus, the example terms “below” and “under” can encompass both an orientation of above and below. The device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein should be interpreted accordingly. Similarly, when a first part is described as being arranged “on” a second part, this indicates that the first part is arranged at an upper side or a lower side of the second part without the limitation to the upper side thereof on the basis of the gravity direction.

Further, in this specification, the phrase “on a plane,” or “plan view,” means viewing a target portion from the top, and the phrase “on a cross-section” means viewing a cross-section formed by vertically cutting a target portion from the side.

It will be understood that when an element, layer, region, or component is referred to as being “formed on,” “on,” “connected to,” or “coupled to” another element, layer, region, or component, it can be directly formed on, on, connected to, or coupled to the other element, layer, region, or component, or indirectly formed on, on, connected to, or coupled to the other element, layer, region, or component such that one or more intervening elements, layers, regions, or components may be present. In addition, this may collectively mean a direct or indirect coupling or connection and an integral or non-integral coupling or connection. For example, when a layer, region, or component is referred to as being “electrically connected” or “electrically coupled” to another layer, region, or component, it can be directly electrically connected or coupled to the other layer, region, and/or component or intervening layers, regions, or components may be present. However, “directly connected/directly coupled,” or “directly on,” refers to one component directly connecting or coupling another component, or being on another component, without an intermediate component. Meanwhile, other expressions describing relationships between components such as “between,” “immediately between” or “adjacent to” and “directly adjacent to” may be construed similarly. In addition, it will also be understood that when an element or layer is referred to as being “between” two elements or layers, it can be the only element or layer between the two elements or layers, or one or more intervening elements or layers may also be present.

For the purposes of this disclosure, expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list. For example, “at least one of X, Y, and Z,” “at least one of X, Y, or Z,” and “at least one selected from the group consisting of X, Y, and Z” may be construed as X only, Y only, Z only, any combination of two or more of X, Y, and Z, such as, for instance, XYZ, XYY, YZ, and ZZ, or any variation thereof. Similarly, the expression such as “at least one of A and B” may include A, B, or A and B. As used herein, “or” generally means “and/or,” and the term “and/or” includes any and all combinations of one or more of the associated listed items. For example, the expression such as “A and/or B” may include A, B, or A and B.

It will be understood that, although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section described below could be termed a second element, component, region, layer or section, without departing from the spirit and scope of the present disclosure. The description of an element as a “first” element may not require or imply the presence of a second element or other elements. The terms “first”, “second”, etc. may also be used herein to differentiate different categories or sets of elements. For conciseness, the terms “first”, “second”, etc. may represent “first-category (or first-set)”, “second-category (or second-set)”, etc., respectively.

In the examples, the x-axis, the y-axis, and/or the z-axis are not limited to three axes of a rectangular coordinate system, and may be interpreted in a broader sense. For example, the x-axis, the y-axis, and the z-axis may be perpendicular to one another, or may represent different directions that are not perpendicular to one another. The same applies for first, second, and/or third directions.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. As used herein, the singular forms “a” and “an” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises,” “comprising,” “have,” “having,” “includes,” and “including,” when used in this specification, specify the presence of the stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

When one or more embodiments may be implemented differently, a specific process order may be performed differently from the described order. For example, two consecutively described processes may be performed substantially at the same time or performed in an order opposite to the described order.

As used herein, the term “substantially,” “about,” “approximately,” and similar terms are used as terms of approximation and not as terms of degree, and are intended to account for the inherent deviations in measured or calculated values that would be recognized by those of ordinary skill in the art. “About” or “approximately,” as used herein, is inclusive of the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art, considering the measurement in question and the error associated with measurement of the particular quantity (i.e., the limitations of the measurement system). For example, “about” may mean within one or more standard deviations, or within ± 30%, 20%, 10%, 5% of the stated value. Further, the use of “may” when describing embodiments of the present disclosure refers to “one or more embodiments of the present disclosure.”

Also, any numerical range disclosed and/or recited herein is intended to include all sub-ranges of the same numerical precision subsumed within the recited range. For example, a range of “1.0 to 10.0” is intended to include all subranges between (and including) the recited minimum value of 1.0 and the recited maximum value of 10.0, that is, having a minimum value equal to or greater than 1.0 and a maximum value equal to or less than 10.0, such as, for example, 2.4 to 7.6. Any maximum numerical limitation recited herein is intended to include all lower numerical limitations subsumed therein, and any minimum numerical limitation recited in this specification is intended to include all higher numerical limitations subsumed therein. Accordingly, Applicant reserves the right to amend this specification, including the claims, to expressly recite any sub-range subsumed within the ranges expressly recited herein. All such ranges are intended to be inherently described in this specification such that amending to expressly recite any such subranges would comply with the requirements of 35 U.S.C. § 112(a) and 35 U.S.C. § 132(a).

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and/or the present specification, and should not be interpreted in an idealized or overly formal sense, unless expressly so defined herein.

FIG. 1 is a diagram showing an application example of an augmented reality (AR)-content-providing apparatus according to some embodiments of the present disclosure.

Referring to FIG. 1 , an AR-content-providing apparatus 111 is integrally formed with a vehicle’s rearview mirror, and is configured to display an AR content image on a car window (e.g., including a windshield or windscreen) WS of the vehicle and/or on a reflective material inside the vehicle. The AR-content-providing apparatus 111 enables the visual AR content images to be provided to a driver and passengers through the car windows WS of the vehicle, and may enable auditory, olfactory, and tactile AR content to be provided through electronic devices. The AR content generated and displayed by the AR-content-providing apparatus 111 may be displayed on at least one other content display device, such as a tablet personal computer (PC).

The AR-content-providing apparatus 111 is integrally formed or assembled with interior materials or indoor devices, such as a center fascia, dashboard, console box, dome light, sun visor, sunroof control box, seat, headrest, etc. in addition to the vehicle’s rearview mirror. An example in which the AR-content-providing apparatus 111 is integrally formed with the vehicle’s rearview mirror will be described below.

The AR-content-providing apparatus 111 allows an AR content image to be superimposed on a real image shown to the driver or passengers through each of the car windows WS located on the front, sides, and/or rear of the vehicle. To this end, the AR-content-providing apparatus 111 displays an AR content image through the car windows WS to which a reflective material is added, or displays an AR content image through a transparent lens (or a refractive lens) of the car windows WS. The AR content image may be a two-dimensional (2D) or a three-dimensional (3D) image obtained by combining at least one of a graphic image, hologram, a shot image, a video, and text.

The AR-content-providing apparatus 111 may further include at least one display module for displaying an AR content image, and optical members. As an example, the AR-content-providing apparatus 111 may include optical members for changing the size, display paths (or optical paths), focuses, and the like of an AR content image displayed on the at least one display module such that the AR content image may be perceived by the eyes of the driver and passengers.

The AR-content-providing apparatus 111 senses a vehicle driving environment, an external environment, and a change in the driver’s body in real time, and generates an AR content for stimulating senses such as tactile, olfactory, and auditory senses in addition to visual image content according to results of the sensing. For example, the AR-content-providing apparatus 111 displays an AR content image on the car window WS, etc. so that the AR content image is superimposed on a real image outside the car windows WS visible to the driver or passengers. In addition, the AR-content-providing apparatus 111 control operations of electronic devices configured to stimulate senses such as tactile, olfactory, and auditory senses. Also, the AR-content-providing apparatus 111 may transmit AR content including an AR content image to at least one other content display device such as a smartphone to support the displaying of the same content on different content display devices.

At least one content display device, other than the AR-content-providing apparatus 111, may be a content display device owned by a driver, a passenger, or the like. The content display devices may display on a screen AR content that is transmitted and received in real time from the AR-content-providing apparatus 111, for example, an AR content image. When AR content data is received from the AR-content-providing apparatus 111, the at least one content display device may output the AR content data to a screen and a speaker at the same timing.

At least one content display apparatus including the AR-content-providing apparatus 111 may be applied to a wrist watch-type electronic device, a head-mounted display, an external billboard, an electronic display board, a medical device, an inspection device, various home appliances such as refrigerators and washing machines, or Internet of Things (IoT) devices. Also, at least one content display device may be a tablet mobile communication device, such as a smartphone or a tablet PC, a personal digital assistant (PDA), a portable multimedia player (PMP), a television, a game console, a monitor of a personal computer, a notebook computer, a flat-panel image display device, a vehicle navigation system, a vehicle dashboard, a digital camera, a camcorder, etc. Here, as an example of the content display devices, a flat-panel image display device mounted on a center fascia, headrest, console box, etc. of a vehicle is described, and the flat-panel image display device may have high resolution or ultra-high resolution such as HD, UHD, 4K, and 8K.

A flat-panel image display device that is used as an image display module or a content display device of the AR-content-providing apparatus 111 may be classified as an organic light-emitting diode (OLED), an inorganic electroluminescent (inorganic EL), a quantum dot light-emitting diode (QLED), a micro LED, a nano-LED, a plasma display panel (PDP), a field-emission display (FED), a cathode-ray tube (CRT), a liquid crystal display (LCD), an electrophoretic display (EPD), or the like. Hereinafter, a micro LED will be described as a content display device or a display module, and unless a special distinction is suitable, the micro LED applied to some embodiments will be simply abbreviated as a display device. However, the embodiment is not limited to the micro LED, and other content display devices listed above or known in the art may be applied within the scope of sharing technical ideas.

FIG. 2 is a front view showing an AR-content-providing apparatus integrally formed with a rearview mirror of FIG. 1 . FIG. 3 is a rear view showing an AR-content-providing apparatus integrally formed with a rearview mirror of FIG. 2 .

Referring to FIGS. 2 and 3 , the AR-content-providing apparatus 111 integrally formed with the rearview mirror includes first to sixth display modules DP1 to DP6 formed on surfaces in a forward direction, a rearward direction, leftward and rightward directions, and a lower direction of the rearview mirror.

The first display module DP1 may be formed on a surface in the rearward direction or in the lower direction of the rearview mirror. The first display module DP1 provides an AR content image to a forward car window of a driver seat, so that the AR content image is displayed through the forward car window and a transparent lens. The forward car window may include a transparent lens, a translucent optical waveguide (e.g., a prism) or the like. Accordingly, the AR content image displayed through the first display module DP1 may be perceived by a driver’s eyes through the optical waveguide, transparent lens, reflective member, or the like of the forward car window.

The second display module DP2 may be formed on a surface in the forward direction or in one side direction of the rearview mirror. The second display module DP2 provides an AR content image to a side car window of a driver seat, so that the AR content image is displayed through the side car window, etc. The side car window of the driver seat may include a transparent lens, a translucent optical waveguide (e.g., a prism) or the like. Accordingly, the AR content image displayed through the second display module DP2 may be perceived by a driver’s eyes through the optical waveguide, transparent lens, reflective member, or the like of the side car window.

The third display module DP3 may be formed on a surface in the forward direction of the rearview mirror. The third display module DP3 provides an AR content image to a rearward car window of a driver seat, so that the AR content image is displayed through the rearward car window, etc. The rearward car window of the vehicle may include a transparent lens, a reflective member, or a translucent optical waveguide.

Also, the at least one sensing module 120 may be additionally formed on an automotive interior material, an interior decoration, or an electronic device other than the rearview mirror. The sensing module 120 senses a distance (or depth) to an object in front, distances to objects on both sides, distances to objects in diagonal directions, distances to nearby vehicles, distances to nearby people or animals, external illuminance, and the moving direction, moving distance, and tilt of a vehicle.

As an example, the image sensors SS1 may be located in a forward direction and a rear direction of the vehicle, and in directions of side-view mirrors. The image sensors SS1 detect images in one of the forward, rearward, leftward, rightward, and diagonal directions of the vehicle in real time. Image data generated through the image sensors SS1 is transmitted to the control module 130 in real time, and is used by the control module 130 to recognize and analyze nearby objects.

Also, the control module 130 detects surrounding information including real-time driving information of the vehicle and surrounding information including distance information between the vehicle and nearby objects, etc. Also, the control module 130 receives vehicle control information. The control module 130 classifies the real-time driving information, control information, and surrounding information of the vehicle according to the display positions of the first to sixth display modules DP1 to DP6, and generates AR content data to be displayed separately for each of the first to sixth display modules DP1 to DP6.

The signal processing unit 133 receives the image data obtained by capturing the surrounding of the vehicle, and analyzes and classifies edge values, luminance values, and/or grayscale values of the image data. Then, the signal processing unit 133 classifies and detects nearby objects and people from the image data according to a result of the analysis, and generates directionality information and location information on the nearby objects and people included in the image data of each direction. The signal processing unit 133 shares the directionality information and the location information on the nearby objects and peoples with the content generation control unit 132. Here, the image data obtained by capturing the surrounding of the vehicle may be image data obtained by performing capturing in at least one of the forward direction, rearward direction, leftward and rightward directions, and/or diagonal directions of the vehicle.

Also, the signal processing unit 133 receives, in real time, the distance sensing signals in at least one of the forward direction, rearward direction, leftward and rightward directions, and/or diagonal directions of the vehicle and generates distance information of objects near the vehicle.

Also, the content generation control unit 132 sorts information rearranged or combined for each of the first to sixth display modules DP1 to DP6 (e.g., in a preset display order), and generates AR content data to be displayed for each of the first to sixth display modules DP1 to DP6. Subsequently, the content generation control unit 132 separately transmits, to the display control unit 131, the AR content data to be displayed for each of the first to sixth display modules DP1 to DP6.

The electronic device control unit 136 generates and transmits operation control signals for operating at least one acoustic device 311, at least one vibration device 312, and at least one fragrance device 313, according to the characteristics of the AR content data.

Accordingly, the communication unit 135 may perform pairing and wireless communication with external content display devices using at least one of a BLUETOOTH® communication scheme, an infrared communication scheme, a Wi-Fi-Direct® communication scheme, and an NFC method.

The communication unit 135 transmits the AR content data that is generated to be displayed for each of the first to sixth display modules DP1 to DP6 to external content display devices, thereby supporting the displaying of the AR content data on the external content display devices. Also, the communication unit 135 may receive biosignal information, such as heart rate information, blood pressure information, and body temperature information, from the external content display devices, and may transmit the biosignal information to the content generation control unit 132. Subsequently, the content generation control unit 132 may generate AR content data including the biosignal information, such as heart rate information, blood pressure information, and body temperature information, and may transmit the AR content data to the display control unit 131.

The display control unit 131 sorts the image data of the AR content data input from the content generation control unit 132 separately for each of the first to sixth display modules DP1 to DP6. Also, the display control unit 131 performs control such that the AR content images are modulated according to display characteristics (or driving characteristics), such as resolution and driving frequency of the first to sixth display modules DP1 to DP6, and displayed on the first to sixth display modules DP1 to DP6.

For example, the electron blocking layer EBL may be p-AlGaN doped with p-type Mg. The thickness Tebl of the electron blocking layer EBL may be about 10 nm to about 50 nm. The electron blocking layer EBL may be omitted.

The active layer MQW may be classified as first to third active layers. Each of the first to third active layers may include a material having a single- or multi-quantum well structure. When including a material having a multi-quantum well structure, each of the first to third active layers may have a structure in which a plurality of well layers and a plurality of barrier layers are alternately stacked. In this case, the first active layer may contain InGaN or GaAs, and the second active layer and the third active layer may contain InGaN. However, the present disclosure is not limited thereto. Here, the first active layer may emit light by recombining electron-hole pairs according to an electric signal. The first active layer may emit first light with a main peak wavelength ranging from about 600 nm to about 750 nm, that is, light in a red wavelength band. The second active layer may emit light by combining electron-hole pairs according to an electric signal. The second active layer may emit third light with a main peak wavelength ranging from about 480 nm to about 560 nm, that is, light in a green wavelength band. The third active layer may emit light by combining electron-hole pairs according to an electric signal. The third active layer may emit second light with a main peak wavelength ranging from about 370 nm to about 460 nm, that is, light in a blue wavelength band.

In the first to third active layers, the color of emitted light may vary depending on the content of indium. For example, the wavelength band of light emitted from each of the first to third active layers may be shifted closer to a red wavelength band as the content of indium decreases and may be shifted closer to a blue wavelength band as the content of indium increases. The content of indium (In) of the first active layer may be higher than the content of indium (In) of the second active layer, and the content of indium (In) of the second active layer may be higher than the content of indium (In) of the third active layer. For example, the content of indium (In) of the third active layer may be about 15%, the content of indium (In) of the second active layer may be about 25%, and the content of indium (In) of the first active layer may be greater than or equal to about 35%.

Because the color of emitted light of each of the first to third active layers may vary depending on the content of indium, the light-emitting device layer 217 of each of the light-emitting devices LE1, LE2, and LE3 may emit the first light, the second light, and the third light in the same wavelength, or may emit the respective light differently, depending on the content of indium. For example, when the content of indium (In) in the first to third active layers of the first light-emitting device LE1 is within about 15%, the first light-emitting device LE1 may emit the first light in the red wavelength band with a main peak wavelength ranging from about 600 nm to about 750 nm. Also, when the content of indium (In) in the first to third active layers of the second light-emitting device LE2 is about 25%, the second light-emitting device LE2 may emit the second light in the green wavelength band with a main peak wavelength ranging from about 480 nm to about 560 nm. Also, when the content of indium (In) in the first to third active layers of the third light-emitting device LE3 is greater than or equal to about 35%, the third light-emitting device LE3 may emit the third light in the blue wavelength band with a main peak wavelength ranging from about 370 nm to about 460 nm. By adjusting and setting the content of indium (In) in the first to third active layers of the fourth light-emitting device LE4, the fourth light-emitting device LE4 may emit the first to third light or may emit fourth light.

The superlattice layer SLT may be located on the active layer MQW. The superlattice layer SLT may be a layer for releasing stress between the second semiconductor layer SEM2 and the active layer MQW. For example, the superlattice layer SLT may be formed of InGaN or GaN. The thickness Tslt of the superlattice layer SLT may be about 50 nm to about 200 nm. The superlattice layer SLT may be omitted.

The second semiconductor layer SEM2 may be located on the superlattice layer SLT. The second semiconductor layer SEM2 may be doped with second conductive dopants, such as Si, Ge, and Sn. For example, the second semiconductor layer SEM2 may be n-GaN doped with n-type Si. The thickness Tsem2 of the second semiconductor layer SEM2 may be about 2 µm to about 4 µm.

The partition walls PW may be spaced apart from the light-emitting devices LE1 to LE4 located in the first to fourth light-emitting areas EA1 to EA4. The partition walls PW may be located to surround (e.g., surround in plan view) the light-emitting devices LE1 to LE4 located in the first to fourth light-emitting areas EA1 to EA4.

The partition walls PW may be located on the common connection electrodes CCE. The width of the partition walls in the first direction DR1 and the second direction DR2 may be smaller than the width of the common connection electrode. The partition walls PW may be spaced apart from the light-emitting devices LE.

The partition walls PW may include a first partition wall PW1, a second partition wall PW2, and a third partition wall PW3. The first partition wall PW1 may be located on the first insulating layer INS1. Because the first partition wall PW1 is formed in the same process as that of the light-emitting device LE, at least a partial area of the first partition wall PW1 may contain the same material as the light-emitting device LE.

The second insulating layer INS2 may be located on side surfaces of the common connection electrode CCE, side surfaces of the partition walls PW, side surfaces of the pixel electrodes 214, side surfaces of the connection electrodes 213, and side surfaces of the light-emitting devices LE1 to LE4. The second insulating layer INS2 may be formed as an inorganic layer such as a silicon oxide layer (SiO₂). The thickness of the second insulating layer INS2 may be about 0.1 µm.

The common electrode CE may be located on upper surfaces and side surfaces of the light-emitting devices LE1 to LE4 and upper surfaces and side surfaces of the partition walls PW (e.g., may surround side surfaces of the light-emitting devices LE1 to LE4 and of the partition walls PW with the second insulating layer INS2 therebetween). That is, the common electrode CE may be located to cover the upper surfaces and side surfaces of the light-emitting devices LE1 to LE4 and the upper surfaces and side surfaces of the partition walls PW.

The common electrode CE may be in contact with the second insulating layer INS2 located on the side surfaces of the common connection electrode CCE, the side surfaces of the partition walls PW, the side surfaces of the pixel electrodes 214, the side surfaces of the connection electrodes 213, and the side surfaces of the light-emitting devices LE1 to LE4. Also, the common electrode CE may be in contact with the upper surface of the common connection electrode CCE, the upper surfaces of the light-emitting devices LE1 to LE4, and upper surfaces of the partition walls PW.

The common electrode CE may be in contact with the upper surface of the common connection electrode CCE at portions that are exposed and not covered with the second insulating layer INS2, and may be in contact with the upper surfaces of the light-emitting devices LE1 to LE4. Therefore, the common voltage supplied to the common connection electrode CCE may be applied to the light-emitting devices LE1 to LE4. That is, each of the light-emitting devices LE1 to LE4 may have one end configured to receive a pixel voltage or an anode voltage of the pixel electrode 214 through the connection electrodes 213, and the other end configured to receive a common voltage through the common electrode CE. The light-emitting device LE may emit light with a luminance (e.g., a predetermined luminance) according to a voltage difference between the pixel voltage and the common voltage.

The reflective layer RF may be located on (e.g., may surround in a plan view) the side surfaces of the common connection electrode CCE, side surfaces of the partition walls PW, side surfaces of the pixel electrodes 214, side surfaces of the connection electrodes 213, and side surfaces of the light-emitting devices LE1 to LE4 (e.g., with the second insulating layer INS2 and the common electrode CE therebetween). The reflective layer RF serves to reflect light traveling not in the upper direction, but instead traveling (e.g., partially) in the longitudinal or transverse direction, among the light emitted from the light-emitting devices LE1 to LE4. The reflective layer RF may include a metal material having high reflectivity, such as aluminum (Al). The thickness of the reflective layer RF may be about 0.1 µm.

A base resin BRS may be located on a passivation layer in each of the light-emitting devices LE1 to LE4. The base resin BRS may contain a transparent organic material. The base resin BRS may further include a scatterer for scattering the light of the light-emitting devices LE1 to LE4 in random directions. In this case, the scatterer may contain metal oxide particles or organic particles.

A light-blocking member BM may be located on the partition wall PW. The light-blocking member BM may contain a light-blocking material. The light-blocking member BM may be located between the adjacent light-emitting areas EA1, EA2, EA3, and EA4 to reduce or prevent mixture of colors of light emitted in different wavelength bands from the light-emitting device LE1 to LE4 of the light-emitting areas EA1, EA2, EA3, and EA4. Also, the light-blocking member BM may absorb at least a portion of external light incident on the light-emitting device layer 217 from the outside to reduce reflection of the external light. The light-blocking member BM may be positioned on the partition wall PW and may be located to extend to each of the light-emitting areas EA1, EA2, EA3, and EA4. That is, the width of the light-blocking member BM may be greater than the width of the partition wall PW.

Each optical pattern LP may be selectively located on a corresponding one of the light-emitting areas EA1, EA2, EA3, and EA4. Each optical pattern LP may be directly located on the base resin BRS of each of the light-emitting areas EA1, EA2, EA3, and EA4, respectively. Each optical pattern LP may have a shape protruding in an upper direction (e.g., in a direction from the light-emitting devices LE1 to LE4 to the corresponding optical pattern LP). For example, the cross-sectional shape of each optical pattern LP may include the shape of an upward convex lens. Each optical pattern LP may be located on the base resin BRS and the light-blocking member BM that are respectively located below. The width of each optical pattern LP may be equal to, greater than, or smaller than the width of each of the light-emitting areas EA1, EA2, EA3, and EA4. In the light-emitting areas EA1, EA2, EA3, and EA4, the optical patterns LP may collect first to third light or fourth light that has passed through the base resins BRS.
